COMBINED GAS AND FUE L STOVE.

SPECIFICATION forming part of Letters Patent No. 617,362, dated January10, 1899.

Application filed November 9, 1897. Serial No. 657,966. (No model.)

To aZZ whom it may concern.-

Be it known that I, CHARLES D. SHEPARD, a citizen of the United States,and a resident of Peekskill, in the county of Westchester and State ofNew York, have invented certain new and useful Improvements in aCombined Gas and Fuel Stove, of which the following is a specification.

This invention relates to cooking stoves and ranges, and has for itsobject an efificient means of heating the oven with gas without thehandling of gas-burners, the burner being a fixture in the oven andwhile not interfering with the ordinary use of the oven with fuel heatis always ready for the application of gas heat. The object is attainedby the means set forth in the accompanying drawings, which when takenwith this specification constitute a full and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same. Referring to the drawings, Figure Iis perspective View of a stove-oven and its surrounding flues,represented as having part of the front plate removed. Fig. IIrepresents the end of the stove with front plate removed, showing theend of the oven and the damper d for use when the stove is to be heatedwith fuel. Fig. III is an elevation of the stoveoven, fines, andgas-burner in cross-section through the center of the oven. Fig. IV is atop view of the end of the stove, representing the top plate of thestove removed and showing the damper and gas-burner connections. Fig. Vis an end view of the gas-burner, partly in section. Fig. VI representsa section of the oven-door, showing a register for admitting air to thegas-burning chamber when the oven is heated with gas.

Reference to Fig. I will disclose the main features of the invention.The end of a stove containing an oven and its surrounding flues isshown, 3 indicating the fire-box and 4 the ash-pit. a represents thestove-oven, with the usual flues on three sides of itz'. 6., the flue 6between the top plate 25 of the stove and the top plate 0 of the oven,the end flue Z, and the bottom flue m. The arrows 1 l 1 1' show thecourse of the products of combustion to be from the fire-chamber 3, overthe top of the oven through flue 6, down at the end of the oven throughflue Z, under the oven through flue m, where the partition "Z deflectsthem to the front of the flue m, whence they pass to the outlet-flue jto the chimney.

In the upper corner of the oven holes hare cut through the end plate ofthe oven to the flue Z, and these holes are covered by a damper d. Theopenings are bordered, preferably, on the flue side with inclinedflanges 0, Figs. II and III, so that the damper-will the more readilyclose by its own weight when it is intended to be kept closed upon theopenings. It is a mere matter of convenience whether these outlets fromthe oven to the flue should consist of two openings or of only one, ormore than two. The damper d is hinged above the openings, as shown, andis adapted to not only close the openings, as shown in Fig. II, but whenthe gas-burner is in use and the holes h are to be open the dampercloses the flue Z above the holes, as shown in Figs. II and III.

A gas-burner 6, Figs. I, II, and III, is affixed to the top plate of theoven. A righthand end View of the burner, as is herein shown, to be usedis represented by Fig. V. It has a corrugated under surface, the apex ofthe corrugations being pierced with small gasoutlets, as shown at 6,Fig. III. A nozzle f, Figs. I and III, for the attachment of a gaspipeis integral with the burner. A pipe extension passes from the burnerthrough the flue Z to the outside of the stove, where the air-supply sand gas-cock u are applied, as in Figs. II and IV. The particularconstruction of the burner, however, is immaterial. It is only importantthat the gas-flames be distributed uniformly over the top of the oven.

As shown in the several figures, the burnerpipe passes through the flueZ below the point where the damper dis hinged, which involves thenotching of the damper around the pipes, as shown at y, Fig. IV.

The damper d is provided with a handle g,

extending through the outer stove-plate. As represented, it has aweighted handle '11 to serve as a counterbalance to the weight of thedamper and keep it close to the outer flueplate when in the positionindicated by the broken lines g 9, Fig. II.

A baffle-plate b is inserted in the oven just below the openings h,supported on lugs y.

The end of the plate opposite the openings is perforated, as at 7t,Figs. I and III, for the escape ofgases from the part of the oven belowthe plate. The oven-door at the corner corresponding with theperforations in the said baffle-plate is provided with a register or anyconvenient equivalent, as indicated in Fig. VI, for the purpose ofadmitting air to support combustion in the bu rner-chamber.

Then the oven is to be heated by means of the gas-burner, the damper (Zis placed in the position shown in Figs. I and III, cutting off flue 6from the flue Z. The gas-flames shooting downward from the burner 6 willheat the baffle-plate, and the heated currents from the chamber abovethe plate will pass into the flue Z from the openings 71 thence to theflue m under the oven, and out through the fluej to the chimney, heatingthe oven on the top, end, and the bottom. As the burner is made to coverthe top plate of the oven, little loss of heat takes place through thesaid top plate.

I do not wish to be limited to any of the constructions as herein shownand described so long as I adhere to the principles of this invention.

Having described my invention, what 1 claim, and desire to secure byLetters Patent of the United States, is-

1. The combination in a stove provided with an oven and a direct fluefrom the firebox of the stove over the top of the oven, down the side ofand under the oven to the outlet-flue, of a gas-burner placed in the topof the oven, a bathe-plate supported in the oven beneath the burner, thespace between the burner and baffle -plate provided with openingsextending through the side wall of the oven communicating with the flueat the side of the oven, and a damper that may be used to close saidopenings when the gasburner is not in use and to open said openings andclose the side flue above said openings when the gas-burner is in use,substantially as herein shown and described.

2. The combination in a stove having an oven and a direct fine from thefire-box over the top of the oven, down the side of and under the ovento the outlet-flue, of a gasburner placed in the top of the oven, aperforated baffle-plate beneath the burner, the space between the burnerand baffle-plate provided with openings extending through the side wallof the oven communicating with the flue at the side of the oven, and adamper that may be used to close said openings when the gas-burner isnotin use and to open said openings and close the said flue when thegas-burner is in use, substantially as herein shown and described.

3. The combination in a stove having an oven and a direct flue from thefire-box over the top of the oven, down the side of and under the ovento the outlet-flue, of a gasburner placed in the top of the oven, aperforated baffle-plate supported in the oven beneath the burner, thespace between the burner and bathe-plate provided with openings throughthe side wall of the oven communicating with the flue at the side of theoven, a damper that may be used to close said openings, or to open saidopenings and close the flue on that side of the said openings which istoward the fire-box, and an airinlet in the oven-door, substantially asherein shown and described.

Signed at Peekskill, in the countyof W'estchester and State of New York,this 21st day of October, A. D. 1897.
